Information on T Type Tires
T type tires have some additional
information beyond those of P type
tires. These differences are
described below.
T145/80D16 is an example of a tire
size.
Note:The temporary tire size for
your vehicle may be different from
this example. Tire Quality Grades
do not apply to this type of tire.
A.T:Indicates a type of tire, designated by the Tire and Rim
Association, that is intended for temporary service on cars, sport-utility
vehicles, minivans and light trucks.
B.145:Indicates the nominal width of the tire in millimeters from
sidewall edge to sidewall edge. In general, the larger the number, the
wider the tire.
C.80:Indicates the aspect ratio, which gives the tire’s ratio of height to
width. Numbers of 70 or lower indicate a short sidewall.
D.D:Indicates a diagonal type tire.R:Indicates a radial type tire.
E.16:Indicates the wheel or rim diameter in inches. If you change your
wheel size, you will have to purchase new tires to match the new wheel
diameter.
Location of the Tire Label
You will find a Tire Label containing tire inflation pressure by tire size
and other important information located on the B-Pillar or the edge of
the driver’s door. See the payload description and graphic in theLoad
Carryingchapter.

on the Safety Compliance Certification Label (affixed to either the door
hinge pillar, door-latch post, or the door edge that meets the door-latch
post, next to the driver’s seating position), or Tire Label which is located
on the B-Pillar or the edge of the driver’s door. The cold inflation
pressure should never be set lower than the recommended pressure on
the Safety Compliance Certification Label or Tire Label.
When weather temperature changes occur, tire inflation pressures also
change. A 10°F (6°C) temperature drop can cause a corresponding drop
of 1 psi (7 kPa) in inflation pressure. Check your tire pressures
frequently and adjust them to the proper pressure which can be found
on the Safety Compliance Certification Label or Tire Label.
To check the pressure in your tire(s):
1. Make sure the tires are cool, meaning they are not hot from driving
even a mile.
Note:If you are checking tire pressure when the tire is hot (for
example, driven more than 1 mile [1.6 kilometers]), never bleed or
reduce air pressure. The tires are hot from driving and it is normal for
pressures to increase above recommended cold pressures. A hot tire at
or below recommended cold inflation pressure could be significantly
under-inflated.
Note:If you have to drive a distance to get air for your tire(s), check
and record the tire pressure first and add the appropriate air pressure
when you get to the pump. It is normal for tires to heat up and the air
pressure inside to go up as you drive.
2. Remove the cap from the valve on one tire, then firmly press the tire
gauge onto the valve and measure the pressure.
3. Add enough air to reach the recommended air pressure.
Note:If you overfill the tire, release air by pressing on the metal stem in
the center of the valve. Then recheck the pressure with your tire gauge.
4. Replace the valve cap.
5. Repeat this procedure for each tire, including the spare.
Note:Some spare tires operate at a higher inflation pressure than the
other tires. For T-type mini-spare tires, see theDissimilar Spare Tire
and Wheel Assembly Informationsection. Store and maintain at 60 psi
(4.15 bar). For full-size and dissimilar spare tires, seeDissimilar Spare
Tire and Wheel Assembly InformationunderChanging a Road Wheel
in this chapter. Store and maintain at the higher of the front and rear
inflation pressure as shown on the Tire Label.

WARNING: Age
Tires degrade over time depending on many factors such as
weather, storage conditions, and conditions of use (such as load, speed,
inflation pressure) the tires experience throughout their lives.
In general, tires should be replaced after six years regardless of tread
wear. However, heat caused by hot climates or frequent high loading
conditions can accelerate the aging process and may require tires to be
replaced more frequently.
You should replace your spare tire when you replace the road tires or
after six years due to aging even if it has not been used.
U.S. DOT Tire Identification Number
Both U.S. and Canada Federal regulations require tire manufacturers to
place standardized information on the sidewall of all tires. This
information identifies and describes the fundamental characteristics of
the tire and also provides a U.S. DOT Tire Identification Number for
safety standard certification and in case of a recall.
This begins with the letters DOT and indicates that the tire meets all
federal standards. The next two numbers or letters are the plant code
designating where it was manufactured, the next two are the tire size
code and the last four numbers represent the week and year the tire was
built. For example, the numbers 317 mean the 31st week of 1997. After
2000 the numbers go to four digits. For example, 2501 means the 25th
week of 2001. The numbers in between are identification codes used for
traceability. This information is used to contact customers if a tire defect
requires a recall.

Tire Replacement Requirements
WARNING:Only use replacement tires and wheels that are the
same size, load index, speed rating and type (such as P-metric
versus LT-metric or all-season versus all-terrain) as those originally
provided by Ford. The recommended tire and wheel size may be found
on either the Safety Compliance Certification Label (affixed to either
the door hinge pillar, door-latch post, or the door edge that meets the
door-latch post, next to the driver’s seating position), or the Tire Label
which is located on the B-Pillar or edge of the driver’s door. If this
information is not found on these labels, then you should contact your
authorized dealer as soon as possible. Use of any tire or wheel not
recommended by Ford can affect the safety and performance of your
vehicle, which could result in an increased risk of loss of vehicle
control, vehicle rollover, personal injury and death. Additionally the use
of non-recommended tires and wheels could cause steering, suspension,
axle, transfer case or power transfer unit failure. If you have questions
regarding tire replacement, contact your authorized dealer as soon as
possible.

WARNING:To reduce the risk of serious injury, when mounting
replacement tires and wheels, you should not exceed the
maximum pressure indicated on the sidewall of the tire to set the beads
without additional precautions listed below. If the beads do not seat at
the maximum pressure indicated, re-lubricate and try again.
When inflating the tire for mounting pressures up to 20 psi (1.38 bar)
greater than the maximum pressure on the tire sidewall, the following
precautions must be taken to protect the person mounting the tire:
1. Make sure that you have the correct tire and wheel size.
2. Lubricate the tire bead and wheel bead seat area again.
3. Stand at a minimum of 12 feet (3.66 meters) away from the tire
wheel assembly.
4. Use both eye and ear protection.
For a mounting pressure more than 20 psi (1.38 bar) greater than the
maximum pressure, a Ford dealer or other tire service professional
should do the mounting.
Always inflate steel carcass tires with a remote air fill with the person
inflating standing at a minimum of 12 feet (3.66 meters) away from the
tire wheel assembly.
Your vehicle is equipped with tires designed to provide a safe ride and
handling capability.
Important:Remember to replace the wheel valve stems when the road
tires are replaced on your vehicle.
The two front tires or two rear tires should generally be replaced as a
pair.
The tire pressure sensors mounted in the wheels (originally installed on
your vehicle) are not designed to be used in aftermarket wheels.
The use of wheels or tires not recommended by Ford Motor Company
may affect the operation of your tire pressure monitoring system.
If the tire pressure monitoring system indicator is flashing, the system is
malfunctioning. Your replacement tire might be incompatible with your
tire pressure monitoring system, or some component of the system may
be damaged.

The tires should also be balanced periodically. An unbalanced tire and
wheel assembly may result in irregular tire wear.
Tire Rotation
Note:If your tires show uneven wear ask an authorized dealer to check
for and correct any wheel misalignment, tire imbalance or mechanical
problem involved before tire rotation.
Note:Your vehicle may be equipped with a dissimilar spare tire and
wheel assembly. A dissimilar spare tire and wheel assembly is defined as
a spare tire or wheel that is different in brand, size or appearance from
the road tires and wheels. If you have a dissimilar spare tire and wheel
assembly, it is intended for temporary use only and should not be used
in a tire rotation.
Note:After having your tires rotated, inflation pressure must be checked
and adjusted to the vehicle requirements.
Rotating your tires at the recommended interval (as indicated in the
scheduled maintenance information) will help your tires wear more
evenly, providing better tire performance and longer tire life.

POLICE TIRES
Wheel rims - police
To withstand the demands placed on vehicles driven under heavy duty
service conditions, Ford Motor Company installs heavy duty wheels.
Tires - police
Tires (including the spare) are speed-rated radials for police use. Use
only the recommended tire size and speed ratings.
In regions with snow and ice during the winter months, installation of
snow tires may be desirable. Snow tires will usually exhibit a drop in dry
pavement handling, but many show an increase in snow and ice traction.
When snow tires are used, they should be installed on all four wheels,
never on the drive wheels only.

Tires - long term storage
Most high performance tires are made with a nylon overlay.
As such, the following steps should be taken to avoid flatspotting when
the vehicles are not used for a period of time.
•Fleets should store the vehicles with 44 psi (303 kPa) in the tires.
•If the vehicle is stored for periods longer than 30 days, it should be
moved several feet at least once during each 30-day period, so that a
different portion of the tread contacts the ground.
•Tire pressure should be reduced to the recommended pressure shown
on the vehicle certification label before the vehicle is placed back into
service.
USING SNOW CHAINS
WARNING:Snow tires must be the same size, load index, speed
rating as those originally provided by Ford. Use of any tire or
wheel not recommended by Ford can affect the safety and performance
of your vehicle, which could result in an increased risk of loss of vehicle
control, vehicle rollover, personal injury and death. Additionally, the use
of non-recommended tires and wheels could cause steering, suspension,
axle, transfer case or power transfer unit failure.
Note:The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when using
snow tires and chains.
The tires on your vehicle have all-weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and cables . If you need to use cables, it is recommended that steel
wheels (of the same size and specifications) be used, as cables may chip
aluminum wheels.
Follow these guidelines when using snow tires and chains:
•If possible, avoid fully loading your vehicle.
•For police sedan, do not use snow chains or cables on this vehicle as
they may cause damage to your vehicle which may lead to loss of
vehicle control.

Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or tire
inflation pressure label, you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that illuminates a low tire pressure
telltale when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible, and inflate them to the
proper pressure. Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator
to indicate when the system is not operating properly. The TPMS
malfunction indicator is combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously illuminated.
This sequence will continue upon subsequent vehicle start-ups as long as
the malfunction exists.
When the malfunction indicator is illuminated, the system may not be
able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the installation of
replacement or alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS malfunction
telltale after replacing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and wheels allow the
TPMS to continue to function properly.
The tire pressure monitoring system complies with part 15 of the FCC
rules and with RSS-210 of Industry Canada. Operation is subject to the
following two conditions: (1) This device may not cause harmful
interference, and (2) This device must accept any interference received,
including interference that may cause undesired operation.

Changing Tires with a Tire Pressure Monitoring System
Note:Each road tire and full-size
spare is equipped with a tire
pressure sensor located inside the
tire and wheel cavity. The pressure
sensor is attached to the valve stem.
The pressure sensor is covered by
the tire and is not visible unless the
tire is removed. Take care when
changing the tire to avoid damaging
the sensor.
You should always have your tires serviced by an authorized dealer.
Check the tire pressure periodically (at least monthly) using an accurate
tire gauge. SeeInflating Your Tiresin this chapter.
Understanding Your Tire Pressure Monitoring System
The tire pressure monitoring system measures pressure in your four road
tires and sends the tire pressure readings to your vehicle. The low tire
pressure warning light will turn on if the tire pressure is significantly low.
Once the light is illuminated, your tires are under-inflated and need to be
inflated to the manufacturer’s recommended tire pressure. Even if the
light turns on and a short time later turns off, your tire pressure still
needs to be checked.
When a new wheel and tire is installed
When one of your road tires is replaced by a new tire and wheel, the
system sensor located in the new tire and wheel needs to be trained to
the vehicle.
System training tools
Tire pressure monitoring system training tools are available through the
Rotunda catalog or through a Ford dealership. The steps for training the
sensors are outlined below.
